Specification of Letters Patent.

Patented July ll, 1916..

Application filed December 15, 1915. Serial No. 66,983.

To all whom it may concern Be it known that I, HENRY N. BENTON, acitizen of the United States, residing at Philadelphia, in the county ofPhiladelphia, and State of Pennsylvania, have invented certain new anduseful Improvements in Power-Operating Devices for Window- Sashes, ofwhich the following is a specification.

My invention relates to improvements in power operating devices forwindow sashes, the object of the invention being to' provide improvedmeans for simultaneously op erating a plurality of pivoted sashes ortransoms such as commonly used in metal frames, and which will insure astrong leverage to open and close the sashes.

A further object is to provide devices of the character stated which canbe manufactured and sold at a reasonably low price, which are capable ofa wide range of adjustment to accommodate themselves to varyingconditions, and which are of extreme simplicity, yet strong and durablein use.

lVith these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying. drawings: Figure 1 is a view in front elevationillustrating a series of pivoted sashes equipped with my improvedoperating devices. Fig. 2 is a broken view of Fig. 1. Fig. 3 is anenlarged plan view illustrating a single unit. Fig. 4 is a view on anenlarged scale partly in elevation and partly in longitudinal sectionshowing the link 14. Fig. 5 is an enlarged view in side elevationillustrating.

the operating mechanism shown in Fig. 3. Fig. 6 is a view inlongitudinal section on the line 66 of Fig. 5. Fig. 7 is'a view inelevation illustrating a modified form of rod connecting mechanism. Fig.8 is a view similar to Fig. 7 illustrating another modi fication, andFig. 9 is a view in section on the line 99 of Fig. 8.

1 represents pivoted sashes which are mounted in a metal frame 2, andwhich may be of any desired construction.

3 and 4 represent supports which constitute a part of the building orstructure, and

5 is an operating chain adapted tobe operated from a distance to turn awheel (Land the latter operatively connected to a spool or drum 7 whichcauses the movement in opposite directions of two rods 8 and 9. The rods8 and 9, at their ends farthest removed from the spool 7 are connectedby a chain 10, passed around a pulley 11 on a bracket 12 fixed tosupport 4.

As the particular means for operating the rods 8 and 9 form no part ofthe present invention, it is unnecessary to go into detail furtherconcerning the same, except to say that some means is provided forimparting a movement to the rods which will cause them to move inopposite-directions.

Each pivoted sash 1 is provided with a pair of operating devices 13 asshown clearly in Figs. 1 and 2. One of each pair of operating devices isconnected to and moved by the rod 9, and the other of each pair ofoperating devices is connected to and operated by the rod 8. As all ofthese operating devices are precisely alike, the de scription of onewill apply alike to all, and attention is especially directed to Figs.3, 4, and 5, which show on an enlarged scale the detail structure of oneof such operating devices. I

Each operating device is provided with a link 14 pivotally connected atone end by a pin '15 to a bracket 16, the latter secured to the mullion17 of the metal frame 2. The free end of the link 14 is bifurcated, andthe perforated ears 18 forming the bifurcated end receive between them,an angle lever 19, and a pin 20, pivotally connects the angle lever atits angle to the bifurcated cars 18. Link '14, at its free end, isprovided with two shoulders 21 and 22 which limit the pivotal movementof the angle lever 19, and while they allow a certain amount of pivotalmovement, such independent movement is slight and is for a purpose whichwill hereinafter appear. A

bracket 23 is secured to the lower bar 24 of sash 1, and a bar 25 ispivotally connected by couplings 26 and 27 at its respective ends withbracket 23 and lever 19 respectively.

The lever 19 is so shaped that its two memi shorter member 19 ispivotally connected to one ofthe rods 8 or 9 as the case may be,

tration that the rod referred to is the rod 9. j Rods 8 and 9 arecomposed of sections WlllCll are connectedby coupling bolts 28, thelatends'of the levers 19. A preferred form of coupling bolt andcooperating parts is shown in Figs. 5'and 6. This bolt 28 is formedwitha T-head 29-having recesses 30 at op "posite sides to'receive theends'of a yoke 31, the latter having a central opening 32 positioned onthe bolt 28.; In this preferred form, the sections 33 which form therods 8 and 9 above referred to are screw-threaded at one end as shown at34, and have eyes 35 at their opposite ends. j V I A coupling 36 isscrewed onto the threaded'end 34, and has an eye 37 at its free end. Theyoke 31- isprojected through the eyes 35 and 37 and when the parts aresecured by meansof the nut 38 screwed onto the bolt 28, the parts arefirmly yet pivotally connected. The'coupling member 36 allows of acertain amount of adjustment to properly fit the 7 parts together. I i

In the modification illustrated in Fig. 7, the bolt construction isprecisely. like that above described, but the rod sections 39,corresponding to the sections 33 are screwthreaded at both ends, andcoupling members tion.

In'the modification illustrated in Figs. 8 and 9, the yoke'3l isdispensed withflind the bolt 40' corresponding to bolt 28, extends'through a central eye 41 in a turn buckle 42, the latter receiving thescrew-threaded ends ofthe rod sections 39, andpermitting the vnecessary'adjustment.

The operation of my improvements is as follows :In Fig. 3, the; normalposition When the rod 9'is drawn to theleft, link 4 Will'swing on'thepivot 15, and lever 19 will turn ongjthe pivot 20 until its member 19engages the shoulder 22, when there can be no further pivotal'movementof the lever, and-the lever 19 and link 14 operate as a single memberwith the pivot 15 as thefulcrum, and eXert' a. strong direct push on thebar 25 to move the'sash to open position. An intermediate position oftheparts is shown in dotted lines in Fig. 3, but it must be understood thatthese pivotal connections are constantly changing their positions exceptthe pivotal connection of lever 19 and link 14, the shoulders 21 and 22serving to limit independent pivotal movement of these parts; I

As each sash 1 is preferably provided with two operating devices such asabove described, a strong leverage and direct pushnected to the bar 25,While the end of the and we will assume for the purposes of illusteralso pivotally connected to the shorter.

'36 are located on both ends of the rod sec-i when'the sash'is closed isshown in full'lines.

ing force is had to open the sash and they can be opened and closed atwill from any ordinary distance at a minimum expenditure of power. 1

Various slight changes might be made in the general form and arrangementof parts described without departing from my invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
